ARP - Proxy ARP best practices

Proxy ARP is a type of ARP that is often linked to poor or misconfigured network designs due to potential issues like broadcast storms and increased network traffic. Despite these drawbacks, it can be useful in scenarios where devices on different networks need to communicate as if they were on the same network. This is particularly true in smaller networks where simplicity of implementation may outweigh security concerns.

Local Proxy ARP is a variation that operates within the same network or VLAN. Similar best practices should be applied to this type of Proxy ARP as well.
